Since it's being discussed, I will throw it out there and say 1.2 will may never be broken on arcade. Not because of skill as I feel there are many players that could do this, but rather motivation. Unless you get a string of minimal/no screwing games, 1.2 requires a lot of time and grinding. To make it worth it, I believe only a bounty put on a 1.2M arcade score will motivate anyone to attempt this.
I thought that motivation around this game would fade when Dean got 1.2 just before KO3. Then I thought so after KO3. Then I thought it after Robbie got the record. Then I thought it when DK seemed to have cooled off to new lows and everything was about IGBY.
Then KO4 happened. Fire thoroughly reignited (geez, it even got me).
It seems to be more "seasonal" nowadays, but never dies completely.
I think that Robbie, Wes, and Ethan have proven over the last few months that motivation is not a problem for at least a few people, money or not.
Some just want/love/need the grind.
This will serve as a place holder, I'm gonna make a post with some additional comments and data regarding these games, the respective strategies employed, and the implications (or lack there of) of these games, with regards to Robbies and Wes' chances at 1.2 in general.
Yes, please. Make sure you post them soon, and that your thoughts and ideas are easy to copy/paste and slightly rewrite...
